山东大鼎钢管厂After the steel pipe is sizing, enter the cooling tower and spray water to cool down. After cooling, the steel tube is straightened. After straightening, the steel pipe is sent to the metal flaw detector (or water pressure test) through the conveyor belt for internal inspection. If cracks occur inside the steel tube, bubbles will be found. After quality inspection, the steel pipe should be selected strictly by hand. After the quality inspection of steel pipe, paint quantity, specification, production batch number, etc.山东大鼎钢管厂精密无缝钢管均执行标准：GB3639-2000冷轧精密无缝钢管GB/T8162-2008结构用无缝管、GB/T8163-2008流体精密无缝管、GB/T3087-2008低中压锅炉精密管、GB/T5310-2008高压锅炉无缝管、GB/T17396-1999液压支柱精密钢管、GB/T6479-2000化肥专用合金管、GB/T3088-1982汽车半轴套管用无缝钢管、GB/T3093-2002柴油机用高压油管、GB/T8713-1988液压和气动缸筒用精密无缝钢管。浆纱机将锥形钻头冲入钢胚中，形成钢管。钢管的内径由钻头直径的长短决定。
Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
山东大鼎钢管厂公式计算钢管的理论重量：W=(D-S)＊S＊0.02466，其中W=钢管每米的重量；S=钢管的公称壁厚；D=钢管的公称外径，光亮管的表面质量i清洁、无氧化层、无裂纹、折叠、轧制、结疤、分离层和条纹。
Domestic pipes are mainly made up of hot rolled or cold drawn and root carbon welded pipes. Precision tubes are usually used under high temperature and high pressure conditions. When pipes are used as boiler tubes for high temperature flue gas and steam, they will be oxidized and corroded. The steel pipe is required to have high durability, high oxidation resistance, corrosion resistance and good microstructure stability. According to the high temperature performance of boiler tubes, the boiler tubes are divided into common boiler tubes and high-pressure boiler tubes. General boiler tubes or high pressure boiler tubes can be divided into various types of pipes according to their needs.高压锅炉用无缝钢管（GB5310-2008）是用于制造高压及其以上压力的水管锅炉受热面用的优质碳素钢、合金钢和不锈耐热钢无缝钢管。5.化肥设备用高压无缝钢管（GB6479-2000）是适用于工作温度为-40~400℃、工作压力为10~30Ma的化工设备和管道的优质碳素结构钢和合金钢无缝钢管。精密管制造方法一般精密管在350℃以下使用。
